there are a lot of ways to keep your fish alive for a long time.some of them are
You can Protect them by keeping your pond covered by a squared net so yyou can feed them and also because the predators cannot peck through the net (assuming they are birds)
If the predators are fox you should keep gnomes and cover the pond with a net, you also shouldn't keep any attractive, bright plants or any vegetables or fruits growing in that area as it will attract the foxes to come and dig it all up.
neutralize your water with additives and do a 20% water change 2 weeks after starting the pond fresh, then a consistent 15-20% water change every week there after
The fish can live as long as about 2 years but if yo eat alive fish the fish will live for about 2 months.
A long time

No, you're not allowed to fish at all.
Well, Comet goldfish are also known as feeder fish. They can live a very short lifespan or a one that lasts about 2 years. They are hardy fish and are meant to be put in ponds like koi are. These fish are related to koi. The fish can grow to about a foot long if they are properly taken care of. You can buy them at your local pet store for about 20 cents. The best way to keep these fish alive and well is to buy them from a trusted fish dealer. These fish can be fed to larger goldfish. They can also start the nitrogen cycle that takes about one month.
That depends more on the fish you are trying to keep. As a general rule most fish can adapt to almost any water conditions as long as it is clean, but not always. Just research the specific fish you are trying to keep to see what pH will work best for it.

It breathes with its gills as long as it is alive.
food to keep them alive
supposedly, yes. Jason Voorhees will be alive as long as they keep making sequels.
Forever. How long can they stay alive underwater? It depends.
I'd say on the ride/walk home and trip to the tank, but no longer than a hour seems best.
